  1. What is the value of x in the equation 3x + 7 = 22?

    Answer: 5

    Subtract 7 from both sides: 3x = 15. Then divide both sides by 3: x = 5. Verification: 3(5) + 7 = 15 + 7 = 22.

  2. What is the area of a triangle with a base of 10 cm and a height of 6 cm?

    Answer: 30 sq cm

    The area of a triangle is calculated using A = ½ × base × height = ½ × 10 × 6 = 30 square centimeters.

  3. Which property states that a + b = b + a?

    Answer: Commutative property of addition

    The commutative property of addition states that changing the order of addends does not change the sum. Similarly, it applies to multiplication.

  4. What is the mean (average) of the data set: 4, 8, 12, 16, 20?

    Answer: 12

    The mean is found by adding all values (4 + 8 + 12 + 16 + 20 = 60) and dividing by the count (60 ÷ 5 = 12).

  5. What is the slope of the line passing through points (2, 3) and (6, 11)?

    Answer: 2

    Slope = (y₂ - y₁)/(x₂ - x₁) = (11 - 3)/(6 - 2) = 8/4 = 2. The line rises 2 units for every 1 unit of horizontal movement.

  6. What is the volume of a rectangular prism with length 5 cm, width 3 cm, and height 4 cm?

    Answer: 60 cubic cm

    Volume of a rectangular prism = length × width × height = 5 × 3 × 4 = 60 cubic centimeters.
